xkaes - I don't know what Sheridan is like, but in the little cowboy town I grew up in, thumbacks were what naughty children placed on the chair of temporary school teachers brought in from the city.
And Sal, "perfectly flat"? That would apply only to a rather small inkjet print held down by the window mat. And even then, the backing board might warp with humidity changes,
along with the print itself. Never say never. But if it works for the size prints you are dealing with, great. It sure doesn't work for big ones (like 30X40 inch ones).
